    Julia Babin Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

    background knowledge relating to the current cell theory‚ the differences between prokaryotes and eukaryotes‚ and the structures and functions found within cells. Once this knowledge is known‚ a person is then able to give their opinion in the debate. In the 1800s‚ the cell theory was developed. This theory states that cells are found in all living things making them the basic units of life and that all cells come from other cells. In order to be classified as a cell‚ the object in question must be able

    The Cell Theory The Cell Theory‚ formed by Anton van Leeuwenhoek‚ Robert Hooke‚ Matthias Schleiden‚ Theodore Schwann‚ and Rudolf Virchow‚ refers to the idea that cells are the basic unit of structure in every living organism. The theory justifies three principles: all living organisms are composed of one or more cells; the cell is the most basic unit of structure‚ function‚ and organization in all organisms; and all cells come from pre-existing‚ living cells. The formation of the cell theory

    A Cell Compared to a Hospital Cameron Browne The main organelle is the nucleus. I think the nucleus is like the hospital administration because the nucleus is the core of the cell that handles everything‚ and the hospital administration handles everything that goes on in the hospital. Without the “cores” for both the hospital and the cell‚ neither could properly functions. The nucleolus is the center of the nucleus‚ and it basically sends out all of the other organelles that work within the

    Hey little guy they call me the nucleus of an animal cell and lucky you I’m going to be your mentor and I’m going to teach you about me. So welcome as a new Ribosome organelle in the cell world‚ I’m going to make you familiar with your new home. We are going to start off with the Cell Membrane. The Cell Membrane is the selective barrier that’s surrounding the cell. Since you’re a newbie you need to know that the cell membrane allows only certain things to pass into it‚ but that’s only if it’s made

    to start class today talking about cells. Believe it or not‚ each and every one of you came in contact with cells over the weekend. The most important thing to remember is this: cells make up living things. They make up us‚ our families‚ our dogs‚ and even the trees that provide shade to your front yard. Today we are going to focus on the cells that make up our bodies. Your skin‚ brain‚ muscles‚ bones‚ and every other part of your body is made up of cells. Cells are the basic building blocks of all

    Prokaryote Organelles: Nucleoid Region: The region in a prokaryotic cell consisting of a concentrated mass of DNA. (The “nucleus” of a prokaryotic cell) The nucleoid instructs all the organelles on what to do. Ribosome: A cell organelle consisting of RNA and protein organized into two subunits and functioning as the site of protein synthesis in the cytoplasm. The ribosomal subunits are constructed in the nucleolus. (Make proteins from amino acids) The nucleoid controls the ribsomes and specifies

    limited‚ nuclear energy is dangerous‚ and then there is solar energy: clean‚ abundant and safe. It is already used around the Earth to give energy to those huge satellites into orbit but also in the surface of the Earth to provide electricity to many houses or other structures in need of energy. Indeed solar energy may be the most important renewable source of energy for the moment. However installations allowing using the solar energy such as solar panels are still very expensive and space consuming
